SHlNGLE-SHAPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 439,224, dated October 28, 1890.

Application filed December 20, 1889. Serial No. 334.369. (No model.)

To all whom it may concern:

Be it known that I, DANIEL W. WILLIAMS, of Fortuna, in the county of Humboldt and State of California, have invented a new and 5 Improved Automatic Shingle-Shaping Machine, of which the following is a full, clear, and exact description.

This invention relates to shingle-shaping machines, the object of the invention being 10 to provide a machine by means of which shingles may be dressed to the required width and their exposed ends cut to such form as may be desired; and to the ends named the invention consists of certain novel construcx 5 tions, arrangements, and combinations of elements, which will be hereinafter fully explained, and specifically pointed out in the claims.

Reference is to be had to the accompanying 2o drawings, forming a part of this specification,

in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a side View of my improved 2 5 shingle-shaping machine in partial section on line a: of Fig. 2. Fig. 2 is aplan view of the machine. Fig. 3 is a view of the forward end of the shaper and its connections. Fig. at is a plan view of one form of shaper. Fig. 5 is 0 a similar view of a modified form of shaper, and Fig. 6 is a front view of a circular shaper and its connections.

In the drawings, 10 represents the main frame of the machine, which serves as the 35 support for shafts 11, 12, and 13, the shaft 12 being provided with a pulley 14, adapted to receive a driving-belt, with a pinion 15 and a friction driving-wheel 16, said wheel 16 running in contact with a small friction-wheel o 17, carried by the shaft 13. In addition to the wheel 17 the shaft 13 carries a pulley 18, over which there is passed a belt 19, that runs in engagement with a pulley 20, carried by a transverse shaft 21, upon one end of which 5 there is mounted a circular trimming-saw 22. The pinion 15 of the shaft 12 engages a gear 23, carried by the shaft 11, and upon this shaft 11 there is mounted a disk or crank-arm 24, provided with a wrist-pin 25, from which 50 wrist-pin there extends a pitman 26, said pitman in turn being connected to a slide or follower 27, that is mounted to ride on ways formed upon the sills of the frame 10.

To the follower proper there is bolted a shaper A,'such shaper having cutting-blades a bolted thereto. The blades a are inclined, as shown, the contour of the blades being that which it is desired to impart to the exposed end of the shingle.

In addition to the shaper, the follower 27 carries two forwardly-extending arms 30, that are shaped recessed on their upper sides to receive and move a shingle-supporting strip 31, said strip riding in ways 12, that are formed in the sills of the frame 10 directly beneath a chute 32. The length of the recesses in the arms 30 is considerablygreater than the width of the supporting-strip 31, so as to allow the arms 30 in the forward throw of the follower to slide under the strip without moving it until after the blades or have finished acting on the shingle, at which moment the" shoulders formed at the inner ends of the arms by said recesses will engage the strip 31 and push it from under the chute to allow the shingle to fall. In the return movement of the followerthe shoulders at the forward ends of the arms will engage the strip and slide it under the chute to support the next shingle. To the follower 27, I connect a second pitman 33, which said pitman is in turn connected to the short arm of a lever 34, that is fulcrumed at c. This lever 34 carries a link 35, that is pivotally connected to a pusher 36, the pusher-body riding in a groove (1, formed in a table 50, that is arranged directly above the line of travel of the lever 34 and in connection with the trimming-saw. The pusher 36 has laterally-extending projections 37, which normally rest above the table but when the pusher is pushed back to the position indicated by dottedlines in Fig. 1 the projections 37 will drop into recesses 37*,formd in the table, thus permitting a shingle to be laid upon the table and pushed forward in ad Vance of the pusher.

In operation a rotary motion is imparted to the shaft 12, which motion, through the medium of the connections above described, will impart a rotary motion to the saw 22 and a reciprocating motion to the follower 27, the motion of the follower acting to rock the lever 34, and thus reciprocate the pusher 36. As the pusher is reciprocated, a shingle is placed in advance thereof, so that one of its edges will bear against a gage or guide 40. Then as the shingle is advanced, its outer edge will be trimmed off by the saw 22, the stroke of the lever 34: being such as to carry the shingle clear of the saw. After clearing the saw the shingle will drop into the chute 32, butt foremost, as indicated by dotted lines in Fig. 1, and will pass downward through said chute until brought to rest by the strip 31, and just after this arrest of the shingle the follower 27 will be advanced, so that the shaper carried thereby will be brought to bear against the butt of the shingle, and said buttend will be trimmed off to correspond to the form of the shaper. Then after the withdrawal of the shaper the shingle will drop out of the chute, the strip 31 at this time being moved from beneath the shingle, thus clearin g the way for a second shingle; but the strip is returned to its normal position in time to arrest the next shingle.

In practice I prefer to form the shapers so that they may be readily connected to or removed from the follower, and to this end I would make the shapers with horizontal flanges 43, said flanges being apertured to receive a retaining-bolt 44, which bolt passes through the follower.

To back upthe shingle when it is being cut- I employ a plate 51.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a vertically-extending chute and sliding support mounted thereunder, of a shingle-shaper provided with forwardly-projecting arms provided with inner shoulders to move the support from under the chute after the shaper has acted on the shingle and outer shoulders to return the support on the back-stroke, substantially as set forth.

2. The combination, with a vertically-extending chute having a reciprocating shinglesupport at its lower end and a trimmer at its upper end, of a reciprocating shaper working across the lower end of the chute above the said support, substantially as set forth.

3. In a shingle-shaping machine, the combination, with a trimming-saw and a means for revolving the same, of a pusher, a pusheroperating mechanism, a shaper, a shaper-reciprocatingmechanism,ashingle-support,and a chute leading from the trimming-saw to the support, substantially as described.

4. In a shingle-shaping machine, the combination, with a shaper-carrying follower and a means for reciprocating the same, of a trimming-saw, a means for revolving the saw, a pusher, a rocking lever, a pitman by which the lever is connected with the follower, a pitman by which the lever is connected with the pusher, and a chute leading from the saw to the shaper, substantially as described.

5. In a shingle-shaping machine, the combination, with a movable shingle-support 31, of a follower, a shaper A, carried by said follower, a means for reciprocating the follower, a chute 32, a trimming-saw 22, a means for revolving the saw, a pusher 36, formed with flanges or extensions 37, a recessed table above which said flanges normally rest, a lever, a means for rocking the same, and a pitman by which the lever and pusher are connected, substantially as described.
